You may know me from MacOS Catalina install, well I downgraded to High Sierra and ran into new problems.

Okay so here's the deal:
I've installed High Sierra 10.13.6 on my PC. Everything ran smoothly, installation went fine, no errors whatsoever.

In my first boot I ran into few problems that I hope to solve, with fellow hackintoshers.

First problem:
Can't boot from SSD

I used the Bootinstall.command, no errors everything went fine (Legacy user). But when I start my PC it doesn't get booted at all. Not even OC, nothing.

Second problem:

Can't restart

Self explantory, verbose mode doesn't show any errors, nothing its just stuck there not restarting.

Third problem:

Nvidia driver not working

I've installed Nvidia driver, tried three different boot args on three different boots

nvda_drv=1;

NvididaWeb=True

nvda_drv_vrl=1

Still nothing.

MY CONFIG:
AMD FX-6300; RAM 8GB DDR3; SSD: 240GB; Mobo: ASUS M5A78L-M/USB3; Nvidia GTX1050 2GB DDR5

OC FOLDER

I followed the guide on Dortania to the letter, ran SanityCheck, everything should be a-okay.

I really need help. Please help me.
